Capillary sphincters are: A. circular muscular walls that regulate blood flow through the capillaries B. under complete control of the voluntary portion of the nervous system C. capable of dilating in order to increase perfusion to crucial body organs D. responsible for constricting to compensate for decreased cell perfusion

A. circular muscular walls that regulate blood flow through the capillaries

Neurogenic shock occurs when A. failure of the nervous system causes widespread vasodilation B. there is to much blood to fill a smaller vascular container C. the spinal cord is severed and causes massive hemorrhaging D. massive vasoconstriction occurs distal to a spinal cord injury

A. failure of the nervous system causes widespread vasodilation

In an acute injury setting, neurogenic shock is commonly accompanied by: A. hypothermia B. tachycardia C. hypovolemia D. diaphoresis

A. hypothermia

Patients develop septic shock secondary to: A. poor vessel function and severe volume loss B. weak vessel tone caused by nervous system damage C. failures of the blood vessels to adequately dilate D. an infection that weakens cardiac contractions

A. poor vessel function and severe volume loss

A 20 year old male has a large laceration to his wrist. He is holding a blood- soaked towel over the wound, but it continues to bleed rapidly. You should A. Apply pressure to the brachial artery. B. Administer high-flow supplemental oxygen C. Apply a tourniquet proximal to the wrist D. Wrap the towel with pressure bandages

Apply a tourniquet proximal to the wrist

when assessing a patient with signs and symptoms of shock, it is important to remember that A. multiple fractures are the most common cause of hypovolemic shock B. blood pressure may be the last measurable factor to change in shock C. the patient's respirations are deep during the early stages of shock D. irreversible shock often responds well to a prompt blood transfusion

B. blood pressure may be the last measurable factor to change in shock

cardiogenic shock may result from all of the following, EXCEPT A. increased afterload B. increased preload C. heart attack D. poor contractility

B. increased preload

All of the following conditions should make you suspect shocked, EXCEPT: A. severe infection B. anaphylaxis C. ischemic stroke D. Spinal injury

C. ischemic stroke

hypovolemic shock caused by severe burns is the result of a loss of A. platelets B. whole blood C. plasma D. red blood cells

C. plasma

to protect vital organs, the body compensated by directing blood flow away from the organs that are more tolerant of low flow, such as A. the brain B. the heart C. the skin D. the lungs

C. the skin

Distributive shock occurs when A. severe bleeding causes tachycardia in order to distribute blood to the organs faster B. temporary but severe vasodilation causes a decrease in blood supply to the brain C. widespread dilation of the blood vessels causes blood to pool in the vascular beds D. an injury causes restriction of the heart muscle and impairs its pumping function

C. widespread dilation of the blood vessels causes blood to pool in the vascular beds

which of the following statements regarding anaphylactic shock is most correct . A)anaphylactic shock occurs immediately after a person is sensitized to an allergen B)sensitized people will experience less severe reactions upon subsequent exposure. C)anaphylactic shock is the result of immune system failure due to a toxic exposure .D) subsequent exposure following sensitization produces a more severe reaction.

D) subsequent exposure following sensitization produces a more severe reaction.
